This domain may have been more isolated from significant thermal events as evidenced by its mid-greenschist or lower metamorphic grades and lack of intrusions outside the suture zones between Central and Eastern zones along the Angelo fault (Tyler et al., 2012; Phillips et al., 2016) 2.4.4 Regional Mineralisation The Palaeoproterozoic Lamboo Province in the East Kimberley region is host to a wide range of mineral deposit styles including orogenic and possibly epithermal gold systems (Occhipinti et al., 2016); current and recently operating mines include Argyle (diamonds), Ridges Iron Ore (iron), Savannah and Copernicus (nickel, copper, cobalt); Halls Creek, Nicolsons and Wagtail North (gold); other mineral deposits include Speewah (vanadium-titanium). Figure 3 shows the locations of the main mineral deposits of the Kimberley. 2.5 Local Geology 2.5.1 Stratigraphy The following descriptions of the geology of the Koongie Park property are derived from the reconnaissance and mapping programs conducted by previous explorers, supported by existing literature and GSWA geological reports. Major tectonic elements represented in the project area include the Central Zone and Eastern Zone of the Lamboo Province, Sally Downs Supersuite, Moola Bulla Basin, and Kimberley Basin (Figure 6). Majority of the property covers rocks of the Central Zone and the Sally Downs Supersuite. A complex history of polyphase deformation and metamorphism obscures primary textures of rocks and original contact relationships between units. The map patterns of the rock units which occur within the Central Zone tectonic unit are complex and thus no figure was available to show their mapped distribution across the project area. Tickalara Metamorphics The oldest rocks on the property are the Tickalara metamorphics dated at 1865–1854 Ma. They comprise interlayered pelite and psammite, with local banded iron-formation and lesser calc-silicate metamorphosed rocks with biotite-muscovite-andalusite-sillimanite-quartz and garnet-staurolite-biotite-muscovite-quartz assemblages. These rocks are sometimes strikingly similar in appearance to those in the KPF, and indeed the KPF was formerly mapped as Tickalara metamorphics. Orth (2002) described an unconformable contact between the Tickalara and overlying KPF exposed at Hanging Tree, where basaltic volcanic facies and sandstone (Tickalara) are directly overlain by ironstone, chert and felsic volcanic facies (upper KPF), with no obvious structural or metamorphic break between the two units. Olympio Formation The Olympio Formation consists of a monotonous sequence of weakly metamorphosed and strongly deformed sediments, thin- to medium bedded mudstone, siltstone, and matrix-supported quartz wacke, greywacke and arkose. Thicker beds include metamorphosed coarse-grained to pebbly, clast-supported quartz sandstone units. 6. Independent Technical Report continued 86
